When mixed with beryllium, it is a neutron source for physical experiments. The radio was used at the beginning of the century until the 30s in medicines.

RADON

luayth10 — 2018-03-17 15:33:36 UTC

ATOMIC NUMBER:86
SYMBOL:Rn
MELTING POINT:-71,15 °C
BOILING POINT:-61,7 °C
GROUP:18
PERIOD:6
PROPERTIES:Radon holds the last place in the group of noble gases in the periodic table. It is the heaviest known gas, is radioactive, and is essentially inert. At ordinary temperatures, radon is a colorless gas, but when it is cooled below its freezing point it gains a stunning phosphorescence.
USES: Radon was used in some hospitals to treat tumours by sealing the gas in minute tubes, and implanting these into the tumour, treating the disease in situ. Other, safer treatments are now more commonly used. In some places, highconcentrations of radon can build up indoors, escaping from the ground or from granite buildings. Home testing kits are available which can be sent away for analysis.

SELENIUM

2018-03-17 17:53:27 UTC

Symbol: Se
Group: 16
Period: 4
Atomic number: 34
Melting point: 221ºC
Boiling point: 685 °C
It is a non metal
Uses: It is useful in photocells, solar cells and photocopiers.
The biggest use of selenium is as an additive to glass.This is because of some selenium's compounds that decolourise glass, while another give a deep red colour. Selenium can also be used to reduce the transmission of sunlight in architectural glass, giving it a bronze tint. Selenium is used to make pigments for ceramics, paint and plastics.
Selenium converts light to electricity as well.

Atomic Number:4
Symbol:Be
Group:2
Period:2
Melting Point: 1.287 °C

Boliling Point: 2.970 °C
USES FOR: It is a relatively rare element in the universe. Beryllium is used in particularly in the aviation industry for made plains.

Other beryllium uses are used as structural materials for high-speed aircraft, missiles, spacecraft and communication satellites. The oxide has a very high melting point making it useful in nuclear work as well as having ceramic applications

Neon

2018-03-18 18:38:41 UTC

MAIN CHARACTERISTICS:
Symbol: Ne
Period: 2
Group: 18
Z: 10
A: 20.180
Melting point: 24.56K= -248.6ºC
Boiling point: 27.10K= -246ºC
SOME FACT:
It´s a nobel gas, it is also practicaly inert, colourless, odourless and tasteless.
It was discovered in 1898 by William Ramsay and Morris Travers along with krypton and xenon.
Most people call luminiscent tubes neon tubes althoght it doesn´t have neon in it.
SOME USES:
It is mainly use to indicate advertaisment, bu it is also use in cathode rays to proyect imiges in monitors and televisions. We can also use it to make gas laser. And finally in its liqud form is use as a cryogenic refrigerant.
